From its base in Canberra, Australia, Marsh Nickel Alloys has built a strong reputation for supplying high-performance materials to global industries. We are proud to extend our expertise to clients in Canberra, Australia, specializing in the manufacture and supply of top-quality Copper Nickel 7030 sheet and plate. Our commitment lies in delivering materials that meet the most demanding specifications, ensuring reliability and longevity for critical projects in harsh environments, backed by our deep understanding of marine and industrial applications.
Copper Nickel 7030, also known as cupronickel, is an alloy primarily composed of 70% copper and 30% nickel, with small additions of iron and manganese for enhanced strength. This specific composition gives the material outstanding resistance to corrosion, especially in seawater, and provides excellent anti-fouling properties. The sheets and plates we supply boast impressive mechanical strength, good ductility, and are easily weldable, making them a robust and practical choice for engineers and fabricators who need a material that can perform reliably under pressure.
